Henson’s Creature Shop, the company’s visual and f/x division, will bring work on the characters in each film using a blend of CGI and animatronics. Producing duties will be handled by co-CEOs Lisa Henson and Brian Henson along with senior VP Jason Lust.

“The Boggart,” originally published in 1993, centers on a family from Toronto inheriting a Scottish castle with a gleeful spirit who’s been playing tricks on residents for generations. It’s to be developed as a live action family feature with Brian Henson (“Muppet Treasure Island,” “Muppet Christmas Carol”) directing.

“The Doubtful Guest,” which debuted in 1957, revolves around acreature that shows up at a family-owned bed & breakfast. It’s the furthest along of the three projects with Brad Peyton (“Evelyn: The Cutest Evil Dead Girl”) directing and Matthew Huffman penning the screenplay.

“Monster Blood Tattoo” is a series of three books, “Foundling,” “Lamplighter” and a third untitled novel, set in the world of the Half Continent, a magical Victorian realm where an orphaned boy embarks on a perilous quest to become an apprentice to a line of monster bounty hunters. No writer or director is attached; Henson Co. hasn’t decided how many features it will adapt from the trilogy.

Henson Co. recently moved toward turning HBO kids show “Fraggle Rock” into a feature by hiring Ahmet Zappa to write a treatment for a pic about the underground denizens.
